        Abstract
        Poly(vinyl alcohol) (PVA), due to its many desirable characteristics is preferred for a variety of applications ranging from 
stabilizing colloids to pharmaceutical, medical and cosmetic field. Polymer-analogue reaction of PVA with functional azides 
leads to new material characterized by film forming property and photosensitivity. This paper deals with some 
characteristics of films obtained from poly(vinyl alcohol) with pendant p-azidobenzoic tested as potential membranes. The 
electric potential in ionic solutions, the behaviour in the presence of water and permeability parameters of films of modified 
poly(vinyl alcohol) were investigated.
